Received a promotion in the app for free same-day delivery, but the order was placed without the promo. Called customer service, spoke with a rude and unhelpful agent who wasted 45 mins of my time before transferring me to his equally rude and unprofessional supervisor. I had a legit promo offer and both guys implied I was somehow being dishonest. I explained in detail what happened and told them I had screenshots as proof and would happily share with them, but they said I should try taking the screenshots to my local store to see if maybe they could do something to help. I was patient and respectful the entire time despite how I was treated, and the supervisor still hung up on me when I was mid-sentence. What kind of a call center supervisor hangs up on a calm, respectful customer after they've been on hold for more than 30 minutes? Maybe if I was being belligerent or abusive but I was simply stating my position and I guess he couldn't handle it. I've been a loyal Lowes customer for almost 20 years but after this experience I will never shop there again.
